These Wire rings consiinte reinforcing beads in the edges ofthe tire arising und are adapted for damping' engagement with theopposite sices of the wheel eiy. Normeily,the disimeier of the inneredge of'eeoh side wei of the casing is somewhat iess than the diameterof the wheel eiiy so thin; the wire rings or benfis in the edges of thecasing muet irst be expended in 'orcier to sent the edges of the casing;upon; the ieiiy. The i remis or rin wiii then contract when resey u tirecasing are preferabl vals, as indicated at 19 in ig. 1, so astofacilitate the application of said casin and the attachment of the Sameto the fe ly of the wheel.

From. the foregoing description, taken in connection with theaccompanying drawing, the construction, manner of use and severaladvantages of the invention will be is successively borne clearly andfully understood. As the load. by the-springs 10, said fsprings will becompressed, thereby cushionmal condition. Thus, all shocks or jars Awill"be absorbed by the wheel tire and not transmitted to the body of thevehicle. The-elimination of the 'usual inflatable inner tube obviatesthe delays, inconvenience and expense incident to the punctures of suchtube. The interposed wooden blocks 18 between the casing and the ellyprevent pinching or cutting of the wall of the casing by the steelsprings, while said blocks and theamm lar rubber band 12 also addmaterially to the resiliency of the tire." The' flanges 13 and 1l on theedges of the band, space the side walls of the casing from the springs1() and thus prevent wear `upon the casing walls in their relativemovement with respect to the springs. It will thus be seen that we haveproduced a wheel tire which will be -very durable in practical use andrequires but fc \v repairs. At the same time, a maximum of resiliency isobtained in the tire structure and it may also be manufactured atrelatively small cost.

split at inter- While we have shown and described the preferredconstruction and arrangement of 40 the several features employed, itisto be vunderstood that the in` ntion is susceptible of i considerablemodilicadon therein and we, therefore, reserve the privilege of adoptingall such legitimate changes as maybe fairly4 45 embodied within thespirit and'scope of the invention as claimed. y

Having thus fully described our invention, what we desire Letters Patentis: I

The combination with a wheel having' a felly, of two series ofcushioning springs, means for detachably clamping the two series ofsprings upon the periphery ofI the ,y y wheel felly, a casing, means fordeta'chably 55 securing the casing to the edves of the wheel folly, anannular, resilient band extendingy around said springs and havinginwardly projecting flanges on its edges holding ,the

series of springs against relative transverse 60 movement, the sidewalls of the casing being h eld in spaced relation to the springs bysaid flanges, said resilient band beingy also provided with outwardlyprojecting, annular ribs' on-v itsoppositc edges, and ber 65 blocksdisposed between -the casing and the ribs on said band. y In testimonywhereof we hereunto aix our signatures in the presence of two witfnesses.
